SPECIFICATION forming part of Letters Patent No. 572,93*?, datedDecember 8, 1896.

Application filed January 5, 1892. Serial No. 417,075. (No model.)

To all whom t may concern.'

Be it known that I, HORACE Wnnns, of Boston, in the county of Suffolk,State of Mas sachusetts, have invented a new and useful Improvement inSole-Nails and Methods of Making the Same, of which the following is afull, clear, and exact description, reference being had to theaccompanying drawings, forming a part of this specification, in explain-[o ing its nature.

The invention relates to ashoe-nail made of wire having an upset headextending upon all sides of the wire, a shank of the gage of the wire,and a point, one side of which is straight or in line with the side ofthe shank, and the opposite side of which is inclined or tapered. Thisnail is made by grasping the wire by jaws or other instrumel'italities asuitable distance apart and then bringing them zo together to upset thesection of wire between them, thereby forming a head, and by severingfrom the side of the wire immediately above the head a long triangularsection and then severing the completed headed nail from 2 5 theremainder of the wire upon the line of the top of the head.

Referring to the drawings, Figure l represents the wire. Fig. 2 showsthe wire with the head upset thereon. Fig. 3 shows the 3o wire with thehead upset and the point formed bythe removal of a section immediatelyabove the head. Fig. 4. is a view of the complete nail.

The wire a is ol' a uniform gage throughout.

3 5 It has the head-forming section a formed in it by upsetting thesection a2, the parts a3 a4 of the wire immediately above and below thehead being held by two pairs of grasping jaws or devices, one pair ofwhich is movable 4o in relation to the other, and one of which may havehead-forming dies. The wire is then weakened immediately above the heada by having a triangular section a5 removed from its side, preferablywhile the lower section aI1 4 5 is held by grasping-jaws and while thesection which forms the point is held confined in part rThis forms thepoint of the.

in a jaw-recess.

next nail in order and also weakens the connection between the headedsection of the wire and the pointed end of the wire, so that it iseasily detachable upon the line a of the upper surface of the head a.This provides a fastening having an upset head formed from wire of auniform gage throughout and extending substantially uniformly on allsides of the wire, a relatively long shank a2 of the gage of the wire,and a cut point a7, formed by the continuation as of one side of thewire, and the long bevel a upon the opposite side, produced by theremoval of the waste-section a5. A nail of this character is desirablebecause it has the hardened head produced by upsetting the wire underpressure, the stille.

tenacious shank of the temper of the original wire, and a cut point,also having the piropcrty o f the original wire, and thereby easilyclenching or upsetting when brought into contact with a turning-surface,the point of the nail not being hardened or made brittle in the act offorming it, as it is liable to be when swaged or otherwise made by anaction which condenses the metal.

Having thus fully described my invention, I claim and desire to secureby Letters Patent of the United States- The improved article ofmanufacture herein described, the same comprising a nail made of wire,having a plain cylindrical shank of the gage of the wire, and a headformed of a section of the wire between two shanks, whereby a section ofthe wire is caused to extend uniformly from all sides of the shank,

and the point of which is formed by the re- Witnesses:
